The untitled project will be produced by Troy Lum (Saving Mr. Banks, The Water Diviner) and Andrew Mason (The Matrix, Dark City), as Variety notes. It’s expected to chronicle Miller’s life, and is inspired by The Lives of Lee Miller, a biography penned by her son Antony Penrose.

The film’s producers have been granted access to important Miller archives — photos, diaries, etc. –preserved all this time largely thanks to Penrose. They’re currently in search of a writer to adapt the material for a script.

Miller, who passed away in 1977 in the UK after battling cancer, was an established figure in both the fashion and art world. She was dubbed a “muse and collaborator” of the surrealist movement, befriending the likes of Pablo Picasso and Jean Cocteau. She also became known for her work as a Vogue correspondent during WWII.

In addition to the Miller biopic, the Oscar-winning Winslet has two films on the horizon, The Dressmaker, a drama set to open in theaters this December, and Triple 9, a crime drama starring Casey Affleck and Woody Harrelson, which is due out early next year.
